Add a new type to define custom regexp

[gustavonecore]

Before you start

• Create a new branch from master using the convention of feature/{ticket-id}-description. For this case will be: feature/5-regexp-type
• Every commit should follow the convention: #{ticket-id} :: {brief-description-of-the-change}.

Example of valid commits

#5 :: Added new regexp type class
#5 :: Refactor of main class in order to simplify strategy

Example of wrong commits

Update of class

5 > Change of logic

Tasks

• Add a new type class to validate if a string match a given regexp
• The string used to identify this type would be: regexp[{expression}] where {expression} will be the regular expression string.
• Add the related test
• Update the example code
• Update the readme

i.e: We want to create a validation code as follow: ^[0-9]{1,6}$

^     : Start anchor
[0-9] : Character class to match one of the 10 digits
{1,6} : Range quantifier. Minimum 1 repetition and maximum 6.
$     : End anchor
