REMOVEthingtoremovethings
Outputs a new thing that is equal to things with all members equal to thingtoremove removed.
The things input must be either a list or a word.
Because the members of a word are single characters, if things is a word, then thingtoremove should be a single character.
REMOVE does not remove multi-character substrings from a word.
