/**
* allows a few variables (eg. row-number) to be used in field-names

* This is mainly used for autorepeat, but other use is possible.
* You need to be aware of the rules PHP uses to expand vars in strings, a name
* of "Row$row[length]" will expand to 'Row' as $row is scalar, you need to use
* "Row${row}[length]" instead. Only one indirection is allowd in a string by php !!!
* Out of that reason we have now the variable $row_cont, which is $cont[$row] too.
* Attention !!!
* Using only number as index in field-names causes a lot trouble, as depending
* on the variable type (which php determines itself) you used filling and later
* accessing the array it can by the index or the key of an array element.
* To make it short and clear, use "Row$row" or "$col$row" not "$row" or "$row$col" !!!
*
* @param $name sring the name to expand
* @param $c int is the column index starting with 0 (if you have row-headers, data-cells start at 1)
* @param $row int is the row number starting with 0 (if you have col-headers, data-cells start at 1)
* @param $c_, $row_ int are the respective values of the previous template-inclusion,
* eg. the column-headers in the eTemplate-editor are templates itself,
* to show the column-name in the header you can not use $col as it will
* be constant as it is always the same col in the header-template,
* what you want is the value of the previous template-inclusion.
* @param $cont array content of the template, you might use it to generate button-names with id values in it:
* "del[$cont[id]]" expands to "del[123]" if $cont = array('id' => 123)
* @return string the expanded name

* Checks if we have an row- or column autorepeat and sets the indexes for $content, etc.
*
* Autorepeat is important to allow a variable numer of rows or cols, eg. for a list.
* The eTemplate has only one (have to be the last) row or column, which gets
* automaticaly repeated as long as content is availible. To check this the content
* has to be in an sub-array of content. The index / subscript into content is
* determined by the content of size for templates or name for regular fields.
* An autorepeat is defined by an index which contains variables to expand.
* (vor variable expansion in names see expand_names). Usually I use the keys
* $row: 0, 1, 2, 3, ... for only rows, $col: '@', 'A', 'B', 'C', ... for only cols or
* $col$row: '@0','A0',... '@1','A1','B1',... '@2','A2','B2',... for both rows and cells.
* In general everything expand_names can generate is ok - see there.
* As you usually have col- and row-headers, data-cells start with '1' or 'A' !!!
*
* @param $cell array with data of cell: name, type, size, ...
* @param $c,$r int col/row index starting from 0
* @param &$idx string returns the index in $content and $readonlys (NOT $sel_options !!!)
* @param &$idx_cname string returns the basename for the form-name: is $idx if only one value
* @param (no ',') is given in size (name (not template-fields) are always only one value)
* @param $check_col boolean to check for col- or row-autorepeat
