General

• I ensured all of our classes have the "Plc" prefix, as I did encounter situations in which very generic type names had collisions and I had to use the fully qualified class name (including the package name). The "Plc" prefix reduces this risk.
• Introduced a PlcFieldRequest / Response classes, allowing PlcRequests and Responses that don't use field information (When calling functions, for example)
• Removed the "RequestItems". Now the data for the plc read responses is contained in the PlcReadResponse/PlcWriteRequest itself.
• Added the concept of a named-field which is in general a Field description combined with a string alias.
• All sub-types of the PlcFieldRequest/Response use these aliases to reference the field they want to access. Resulting in an API that is more similar to JDBCs RecordSet.
