The string can start with '-' if it is a negative number or '+' for a positive number
- returns
the Long value of the input String
- def processString(msg: String, subst: Map[String, String]): String
Replaces the value found in a string surrounded by <%= ...
Replaces the value found in a string surrounded by <%= ... %> by a replacement according to the value found in the subst Map.
Throws an exception if no correspondance can be found.

a list of trimmed parts whose length is > 0
- def snakify(name: String): String
Turn a string of format "FooBar" into snake case "foo_bar"
Turn a string of format "FooBar" into snake case "foo_bar"
Note: snakify is not reversible, ie. in general the following will _not_ be true:
s == camelify(snakify(s))
