METRON-830 Adding StringFunctions to Stellar - chop, prependifmissing,
appendifmissing and countmatches
## Contributor Comments
Added stellar functions and unit tests for the following:
chop -> Remove the last character from a String.
prependifmissing -> Prepends the prefix to the start of the string if the
string does not already start with any of the prefixes.
appendifmissing -> Appends the suffix to the end of the string if the
string does not already end with any of the suffixes.
countmatches -> Counts how many times the substring appears in the larger
string.
