Provided computation expression builder with custom operation

Overview

This is intended to demonstrate the ability to use a type provider that generates a computation expression builder that defines a custom operation.

Issue #386

Although the provided type seems to work (see Builders.il), the consumption of the builder fails with message:

ProvidedCustomOperation/Usage/Program.fs(12,5): error FS0039: The value or constructor 'add' is not defined. [ProvidedCustomOperation/Usage/Usage.fsproj]
ProvidedCustomOperation/Usage/Program.fs(13,5): error FS0039: The value or constructor 'add' is not defined. [ProvidedCustomOperation/Usage/Usage.fsproj]
