Resolve "Enhacement proposal: LCM text replace operator"

João Capuchorequested to merge
45-enhacement-proposal-lcm-text-replace-operator into develop

Implements a text replace operator by defining a new block with three inputs:

  • The text that will be modified (input)
  • The text whose occurrences will be replaced (before)
  • The text replacement (after)

This then generates Java code using the replace() method, roughly as follows:

input.replace(before, after)

That will replace all occurrences of before in input with after.

Closes #45 (closed)
