+/**
+ * In order to build complex electromagnetic fields, the following class has been built. 
+ * It allows the superposition of an electric field and a magnetic field. 
+ *
+ * The main reason for this is that the field manager attached to a given volume do not handle such a 
+ * superposition. In the case of the sample chamber, this is a big problem because we have to handle 
+ * the electric fields of the ring anode and of the sample cryostat as well as the magnetic field over the sample. 
+ *
+ * The electromagnetic field in the sample region (gate valve chamber + mcp2 chamber) is then the 
+ * superposition of the following fields:
+ * -# electric field for left side of the ring anode
+ * -# electric field for right side of the ring anode
+ * -# electric field for sample cryostat
+ * -# magnetic field for sample region
+ * .
+ * On the same principle was built the class LEMuSRElFieldMix
