DBLib:
	#DBLib()
		creates new Instance
	#DBLib($host,$user,$pass,$database)
		creates new Instance with connection, no need for calling connect()
	-connect($host,$user,$pass,$database)
		returns true/false
	-close()
		void
	-update($target, $values, $identifier=array(), $increment=false)
 		returns boolean success
	-insert($target, $values)
		returns boolean success
	-delete($target,$identifier,$extra="")
		returns boolean success
	-select($target, $values, $identifier=array(), $extra="",$escapeIdentifier=true)
		returns array('row0[]','row1[]'...) or false
	-selectRange($target, $values, $range, $extra="",$escapeIdentifier=true)
		returns array('row0[]','row1[]'...) or false
	-tableName($table)
		returns tablename with prefix
	-dbEscape($string)
		returns escaped string (if connected, otherwise unaltered string is returned
	::version
		returns version (double)
	-toggleDevmode()
		toggles Devmode on/off [Default:off]
	-isDevmode()
		returns boolean state of devmode
	-setPrefix($prefix)
		sets table-prefix
	-getPrefix()
		returns table-prefix
	-setNoExecute($set=false)
		if $set is true, no queries will be sent, until called again with false
		!!Will echo html-escaped statements ('noExecute') instead of query, methods will return false!!
		connect will return true
		to allow functions to work, connection-state will be set true, though no connection is created
		establishing a connection, enabling noEx, then calling close() wont close the connection
	-isConnected()
		returns boolean state of connection
	#toString:
		If connected, user, host and database, plus version, execute- and devmode-states are returned,
		otherwise only version

	.checkExecute($message)
		checks if execution is enabled, if not $message with NoEx-tag ist echoed and false returned
	.echoDev($message)
		if devmode enabled, $message ist echoed in HTML-comment-tag
	.convertIdentifier($identifier,$escapeIdentifier=true){
		converts $identifier-string or -array to SQL-WHERE-statement
	.convertTable($tables)
		converts $tables-string or -array to SQL-table selection

Connecting using the parameters at the constructor will not return success, so calling ->isConnected() later is recommended, altough calling functions while not connected will return falses

###ARGUMENTS###
$table		(string)		tablename without prefix
$values		(string)		values(columnNames/fields) to be selected or incremented
$values		(array('field'=>'value'))		values to be inserted
$identifier	(array('field'=>'value'))		search criteria
$extra		(string)		is put behind "WHERE", escaped
$escapeIdenitfier	(bool)		true : `column`='value' ## false : column=other_column
$range		(array)		[0]: field; [1]: from; [2]: to
$increment	(bool/int)		if !=false, '$values'='$values'+$increment
