cape.pyfun.lineLoad: Sectional loads module

This module contains functions for reading and processing sectional loads. It is a version of cape.cfdx.lineLoad that is closely tied to cape.pyfun.dataBook.

It provides the primary class DBLineLoad, which is a subclass of cape.cfdx.dataBook.DBBase. This class is an interface to all line load data for a specific surface component.

For reading the sectional load for a single solution on one component (which includes multiple coefficients), there is another class CaseLL.

Finally, reading seam curves from individual cases utilizes the class CaseSeam.
