- also use tmp::New forwarding internally

- the full tensor also supports zip/unzip rows/cols
  and unzipRow, unzipCol, unzipDiag

- also support transposed construction when given a set of vectors

- save in META-INFO/build-info for later re-compilation without git.
  This improves tracking beyond simply referring to the the patch level.

  The information is tagged with an underscore to distinguish from
  "real" build information when git is available.

STYLE: improved shell syntax, pushd/popd guards etc.

  - Previously, the default mapping method was `planarInterpolation` which was
    silently suppressed by the default 'interpolate{R,U,L}=false'.

  STYLE: changes:
            `0` to `Zero`,
            `lookupOrDefault` to `getOrDefault`
         improves header documentation

-  make constructors explicit, delete unused constructors

- silently deprecate 'startsWith', 'endsWith' methods
  (added in 2016: 2b143606), in favour of
  'starts_with', 'ends_with' methods, corresponding to C++20 and
  allowing us to cull then in a few years.

- handle single character versions of starts_with, ends_with.

- add single character version of removeEnd and silently deprecate
  removeTrailing which did the same thing.

- drop the const versions of removeRepeated, removeTrailing.
  Unused and with potential confusion.

STYLE: use shrink_to_fit(), erase()

- Duplicate entries are handled by overwriting, which corresponds more
  closely to the notion of assignment

Example - create p-rgh from p:

    pressure-p-rgh
    {
        type            pressure;
        libs            (fieldFunctionObjects);
        writeControl    writeTime;
        mode            static;
        rho             rhoInf;
        rhoInf          1;
        hydrostaticMode subtract;
        g               (0 -9.81 0);
        hRef            0;
    }

- the hydrostaticMode entry is optional - setting is shown during construction
- g and/or hRef values are retrieved from the database if not specified

- similar prefixing as the dependent readers, making it easier to
  identify

- add FOAM_API information as server module version

- can assist diagnosing when things have gone wrong

- wmake -version, --version option (alias for -show-api)
  for consistency with standard system tools

- move left/right positions prior to substr

- fix typo

- now indicate that the dictionary entry is missing, not that it is
  an unknown function type.

- reduce code duplication, support returning multiple interpolations
  as a Field
