/**
* <p>Reads triumf db-files. Intended for the nonMuSR data.
*
* <p>The file format definition is:
* The following is a description of the features of the TRIUMF .db file format that are
* currently recognized by musrfit/musrview. The available commands include: title, abstract,
* comments, labels, and data.
*
* \verbatim
* TITLE
* The following line must contain the title.
*
*
* ABSTRACT
* The abstract is read in starting with the following line until an empty line is reached.
*
* COMMENTS
* The comments are read in starting with the following line until an empty line is reached.
*
*
* LABELS
* One label must occupy each subsequent line until an empty line is reached. The number
* of labels should preferably match the number of variables in the data.
*
* DATA
* On the same line as the DATA command, there must appear a comma-delimited list of variable
* names. These names should be kept short (some applications truncate to 4 characters). The
* numerical data is read in beginning with the following line until an empty line is reached.
*
* In every line, there must appear exactly 3 comma-delimited fields for each specified name.
* The first field is the value, the second is the positive error, and the third is the negative
* error. If you leave the last field blank (the comma is still required), then the positive error
* will be interpreted as a symmetric error. If you include only the value, then the errors will be
* set to zero.
*
* To reiterate, if you provide a DATA command with 2 names, e.g. "DATA 1st, 2nd", then every subsequent
* line must contain 2*3 - 1 = 5 commas. If you give 3 names, then there must be 3*3 - 1 = 8 commas.
*
* Example
* TITLE
* Most Excellent Fake Data
*
* ABSTRACT
* This data was collected over
* many minutes of light work
* that was required to make it up.
*
* COMMENTS
* This data was generated using C++.
* The file was formatted with Emacs.
*
* LABEL
* Randomized Linear
* Randomized Gaussian
* Randomized Lorentzian
* Run
*
* DATA line, gauss, lrntz, run
* -1.966, -0.168, -0.106, 0.048, 0.002, 0.005, 0.184, 0.010, 0.017, 1001,,, run 1001 title
* -1.895, -0.151, -0.128, 0.014, 0.001, 0.001, 0.259, 0.017, 0.015, 1002,,, run 1002 title
* -1.836, -0.127, -0.184, 0.013, 0.001, 0.001, 0.202, 0.017, 0.020, 1003,,, run 1003 title
* -1.739, -0.064, -0.166, 0.057, 0.003, 0.004, 0.237, 0.016, 0.018, 1004,,, run 1004 title
* -1.601, -0.062, -0.147, 0.104, 0.008, 0.006, 0.271, 0.012, 0.025, 1005,,, run 1005 title
* . . . . . . . . .
* . . . . . . . . .
* . . . . . . . . .
* Alternatively, the data often utilizes the continuation character ('\') and is labelled like so...
* DATA line, gauss, lrntz
* linear = -1.966, -0.168, -0.106, \
* gaussn = 0.048, 0.002, 0.005, \
* lorntz = 0.184, 0.010, 0.017, \
* 1001,,, run 1001 title
* linear = -1.895, -0.151, -0.128, \
* gaussn = 0.014, 0.001, 0.001, \
* lorntz = 0.259, 0.017, 0.015, |
* 1002,,, run 1002 title
* linear = -1.836, -0.127, -0.184, \
* gaussn = 0.013, 0.001, 0.001, \
* lorntz = 0.202, 0.017, 0.020, |
* 1003,,, run 1003 title
* . . . .
* . . . .
* . . . .
* If there is a run line as in the above examples, it must be at the end of the data and given
* in this just slight odd manner (do not blame me, I haven't invented this format ;-) ).
* \endverbatim
*
* <p>Some db-files do have a '\-e' or '\e' label just between the DATA tag line and the real data.
* This tag will just be ignored.
