/*

This function extracts a field value (e.g. tcp.len) from a tree. Because a packet may contain
|
|
multiple values for the the field the extracted values are returned in a result_array. The
|
|
number of array entries is returned in element_count.
|
|
|
|
Return is 0 if all went well. If this function return -1 it is probably because the tree did not
|
|
include the field defined by the field_id.
