Subject: Add NotNull and NotBlank parameter validation

Modified the ParameterValidator to support new NotNull and NotBlank
annotations indicating that a field should not be null or blank.
These annotations can be made at class level or individual field level.

Moved annotations to their own subdirectory.
Added a comment to a method.
Extracted constant strings.
Moved one annotation to the subclass level.

Added support for "Min" annotation.

Propagate validation errors up from nested items.  Apply
field-level validations, even when field is a ParameterGroup.
