The OOXML spec defines the font sizes (the `sz` element) as a double, so the value needs to be wrapped in `PHPExcel_Shared_String::FormatNumber()` to avoid breaking in non-English locales.
`RichText` tries to extract container cell's font via
`Cell->getParent()->getStyle(...)`, which crashes because
`getParent()` does not return a worksheet. Changing it to
`getWorksheet()` fixes the problem.
If $a or $b are not strings, you can get an error that fmod needs param 1 ($a) to be of type double.
MS Excel does not fall over when you insert an empty string in MOD, so I'm guessing PHPExcel should do the same?
For (still) unknown reasons, PHPExcel detects a wrong field type.
If there is no BSE Index, we will fail here and other fields are not read.
So if the BSE Index < 1, continue with the next field.
TODO: Why is there no BSE Index?
Is this a new Office Version?
Password protected field?
More likely : a uncompatible picture
PHP Notice: Undefined offset: -1 in Classes/PHPExcel/Reader/Excel5.php on line 1063

removeColumn doesn't remove all cells, because CacheBase::deleteCacheData only unsets cell data if they are objects.
But cached cell data could be arrays.
I moved the unset from inside the if block (line 150 ff) to after the if block.
BaseReader called `isValidFormat` despite it doesn't require it to be
implemented. Instead we replaced `isValidFormat` by a proper implementation
of `canRead` in each classes. This also remove the semantic amibguity between
those two methods.

This is to fix the situation when cells merged vertically are ignored in columns auto size calculations.
I also removed $calculateMergeCells param as it wasn't used and I believe the only situation when you
want to calculate the width of merged columns has been covered here (and there's no reason to not calculate it).
FIX#46
Some references to classes were incorrectly assumed to be a reference
to self, whereas they were references to classes in global namespace
outside of this project.
FIX#37
GD is implicitly required for saving images anyway, this exception when
it's not loaded simply gives more information on what to do if the
execution flow reaches a places that depends on a function from GD.
```php
<?php
$array = array(
'str' => 'foo',
'num' => 12345,
'null' => NULL,
);
print intval(isset($array['null'])) . PHP_EOL;
print intval(array_key_exists($array['null'])) . PHP_EOL;
print intval(isset($array['num'])) . PHP_EOL;
print intval(array_key_exists($array['num'])) . PHP_EOL;
print intval(isset($array['str'])) . PHP_EOL;
print intval(array_key_exists($array['str'])) . PHP_EOL;
```
Only for this special case, you need array_key_exists(), else avoid it as it is
painfully slow and hurts your performance.
