Problem:
The indicators on the "Collectors (SCAs)" and "Receivers (HCEs)" pages for the trough models:
Collector types in loop configuration: Cold - 1 - 1 - 1 - 1 - 1 - 1 - 1 - 1 - Hot
Receiver types in loop configuration: Cold - 1 - 1 - 1 - 1 - 1 - 1 - 1 - 1 - Hot

do not reflect the configuration of the Single Loop Configuration widget on the Solar Field page. The collector configurations appears to show in the receiver indicator and vice-versa.

Explanation:

1. The UI widget starts the convention of SCA first at index 0 and HCE second at index 1, or [SCA, HCE]
2. The Sca_info_array(), which is called by the UI and during verify() before the SSC model is run, flips the convention from [SCA, HCE] to [HCE, SCA]
3. The SSC submodel that uses this parameter, csp_solver_trough_collector_receiver.cpp, uses the convention [HCE, SCA], so the flipping by Sca_info_array() is warranted.

The problem arises because the UI reuses Sca_info_array() when displaying the SCA and HCE indicators on the respective UI pages, respectively. Since Sca_info_array() flips the convention for the sake of the SSC submodel, the indicator should not have the same convention as the UI widget, it should be flipped. And this is what was likely the confusion when this was implemented.

Solution:
Flip the convention in the '$MIMO$ collectors in field' and 'receivers_in_field' Equations on the "Physical Trough Collector Header" and "Physical Trough Receiver Header" UI Forms.
