Support for multi-column (1 and 2) cvsubsection

[madhur4127]

Currently the environment cvsubsection provides fixed numbers of columns — 3.

If the text in middle column is long with left and right columns being under unutilized still there is a need to break the text in middle column over several lines, which wastes space.

Illustration:

---

A single line could suffice for this long title provided there is a single column instead of 3.

Code:

\begin{cvsection}{Additional Experience and Awards}
    \begin{cvsubsection}[3]{}{Gayle's Sample CV Experiences and awards}{}
        \begin{itemize}
            \item \textbf{Instructor (2003 – 2005):} Taught two full-credit Computer Science courses; average ratings of 4.8
            \item \textbf{Third Prize, Senior Design Projects:} Awarded 3rd prize for Synchronized Calendar project, out of
        \end{itemize}
    \end{cvsubsection}
\end{cvsection}

If somebody needs a quickfix, paste these lines before \makeatother at the very end:

\newenvironment{cvsubsectioncenter}[2][1]{
	\notblank{#2}{\toggletrue{centertitledefined}}{}
	\ifboolexpr{togl {centertitledefined}}{
		\begin{center}
			\textbf{#2} \linebreak
		\end{center}
		% Add space according to the specidied number of lines
		\ifnumcomp{#1}{=}{1}{\vspace*{\aftersinglelinesubsectionheaderspace}}{
			\ifnumcomp{#1}{=}{2}{\vspace*{\afterdoublelinesubsectionheaderspace}}{
				\vspace*{\aftermultilinesubsectionheaderspace}
			}
		}
	} {
		\vspace*{\afteremptysubsectionheaderspace}
	}
	\togglefalse{centertitledefined}
	\begin{adjustwidth}{\subsectionmargin}{\subsectionmargin}
}
{
	\end{adjustwidth}
	\vspace*{\aftersubsectionspace}
}

Now the required functionality is available by using

\begin{cvsubsectioncenter}[number of lines -- optional]{title}
........
\end{cvsubsectioncenter}

instead of vanilla 3 column cvsubsection.
