Functional Provider Manager

[cgrinker]

A lot of providers are single methods. To get our speed to virtual lookup levels of speed for dynamic provider calls we should build a provider manager which stores the function calls in a specific sequence. Additionally that provider manager should provide call and try_call helpers. We can then place these functions in sequence in memory. The full provider manager class can be in a separate dictionary. The included implementation should be able to take lambdas, references to static functions, and full implementations.

It would be nice to benchmark this one.

Examples:

• PParse
• PIdentifier
• PStringer
• PObjectContextual's contextualize
• PEntityAware
