Modifiers

Modifiers and Multipliers
1. modifiers will alter the number of times a character, set or sub expression will be applied.
2. one or more - a plus (+) will allow of one or more of the previous character, set or collection
   • wil+ = wil, will, willl, willlllll
3. zero or more - an asterisk (*) will allow for zero or more of the previous character, set or collection
   • wil* = wi, wil, willl, willlll
   • wi.* = wi, wix, widsw, wifhghhv
4. exists or not - a question mark (?) means that the previous character may or may not exist.
   • wil? = wil or wi
   • wil?t = wilt or wit
5. strict number ranges - to define a strict number range you use curly braces({})
   • {single number}
   • {min amount, max amount}
6. Modifiers are GREEDY and will match everything they can. Use a ? after each modifier to make it match as little as it can.
