Offset - optional params

[pLeBlanc93]

The Offset method behaves differently with the following VALUEINFO:

• Source - fails to find a line
• Source|| - finds the line and applies an offsetVal of 5

Only works with intersecting lines since 0 is treated as the Neighborhood.

The Offset and Neighborhood args could be made optional, resulting in the following scenarios:

• Source - find the intersecting line and populate the point location (not very useful, but possible)
• Source|Offset - find the intersecting line and populate the point location of a tangent offset
• Source||Neighborhood - find the line within x units and populate the point location if it were on the line
• Source|Offset|Neighborhood - find the line within x units and populate the point location if it were on the line + the tangent offset (current implementation)

In short, making the final two arguments optional gives useful functionality.
