A model is created to describe the efficiency of a boiler with both firing rate and inlet temperature. This moves the old BoilerPolynomial to BaseClasses.PartialBoiler. The latter is then extended to the new BoilerPolynomial and BoilerTable.
This closes #2651.

@JayHuLBL : Please approve if the revisions address your review comment.

Q_flow_nominal was removed because this value depends on the size of the equipment, so no default should be provided. The m_flow_nominal assignment is removed because it uses dT_nominal, which has been removed in a previous commit

Please see the inline comment regarding the lower vs higher heating value for which the efficiency curves are specified.

In preparation, the usersguide is partially rewrote so that the description of equations correspond to the model text equation by equation. Some explanatory texts are also rearranged to improve clarity. Some redundant or duplicate documentation left behind in #2695 is cleaned out.

* improved the usersguide

In preparation, the usersguide is partially rewrote so that the description of equations correspond to the model text equation by equation. Some explanatory texts are also rearranged to improve clarity. Some redundant or duplicate documentation left behind in #2695 is cleaned out.

* implemented boiler correction

The changes are very small and I suspect that it was caused by my using Ubuntu 20 instead of 18. But I am pushing it anyway so that it could be tested by someone else.

* Revised documentation, removed trailing white spaces

* Removed trailing white spaces

Done by running for ff in Fluid/Boilers/*; do sed -e 's/ *$//g' -i Fluid/Boilers/BoilerPolynomial.mo; done;
