Consent to act form created in html and called, once change company name
form has been submitted.

Validation method added to ConsentToAct.pm (Controller). Checks the
number of characters inputted by user and the number of fields entered
(should be 3 of the possible 7).

Once validated, user will see summary page.

Tried to abide by MVC but encountered problems separating the validation
method in a separate class from controller, ConsentToAct.pm
