FINDEPOCHNODE - find an occurrence of an epochnode in an array of epochnodes
INDEX = ndi.epoch.findepochnode(EPOCHNODE, EPOCHNODEARRAY)
Returns the index of any occurrence(s) of EPOCHNODE in EPOCHNODEARRAY.
EPOCHNODE and EPOCHNODEARRAY should be structures of the type returned by
ndi.epoch.epochset/EPOCHNODES.
EPOCHNODE should be a single element, and EPOCHNODEARRAY can be an array of
epochnode structures.
If any fields of EPOCHNODE are empty or are not present in the structure,
then that field is not searched over. Thus, INDEX can be an array of all
nodes that match the other criteria. If EPOCHNODE is fully filled, then
only exact matches are returned.
Note: at present, the 'epochprobemap' field is not compared.
