Read Delimited Spreadsheet.vi

[cy...]

can we have an option of loading only user-specified rows from a delimited spreadsheet instead of all rows, perhaps allowing the user to specify which and how many rows to read? this is potentially useful if the user want to read the select or latest few rows (typically at the last few rows due to write append) without having to load unnecessarily large amount of data into memory.

implementation wise, can use a row index and length input optional terminals defaulted at index:0 and length:-1, to yield all rows by default for the rows (note: terminal name changed) output terminal. index:-1 to specify from end of file and non-zero length:L for how many rows from the end of file (-L for reversed order, last row on top). if index:-1, the data read will be replacing elements within a fixed sized array of L elements until the EOF returns true. for example, index:-1 and lenght:5 would yield last 5 rows from file. 

thanks for reading and have a great day
