Acceptance criteria:
External systems (eg GOBI) can apply fund and expense class when creating orders

Approach:
Between fund code and expense class code splitter must be ":"

Example : "fundCode1234:electronicPrn"

Information:
External systems generally only support Fund codes and the sending of a fund code. For this reason it might make sense to use expense class codes as extensions and maintain a list of all fund code+extentions that can be used to Map Fund codes and expense classes when creating orders.
External systems (eg GOBI) may have customizable fields that could be used to send the additional expense class information separately from Fund code.
