SES interceptor - Custom routes can now distinguish between numeric and alphanumeric placeholders just add :varname-numeric

This is an interesting one I have found an interesting way to go about it. A custom route is defined by adding a variable placeholder with :varname. There are two types of variables we can check for:

1. alphanumeric
2. numeric.

The default will be alphanumeric, no need to add anything to the variable, just declare it in the same way. However, for numeric patterns a simple pattern can be placed:

route="/myroute/:id-numeric"

This will tell the routing engine that id has to be numeric. Else, its not a route match. So if you need a numeric variable, the easiest way will be to add a -numeric tag to the variable name. This feature will enhance the routing system and make it even more flexible.
